For a fixed QuantumCircuit with custom unitary gate matrix, QiskitAer is producing different statevector simulation results for qiskit v.1.2.4 and v.1.3.0 The gate matrices defining the custom unitary ...

When combined with Qiskit software tools, the 156-qubit R2 Heron quantum processor can perform 5,000 two-qubit gate operations — double the previous best — meaning it's ready for complex ...

Qiskit is now quantum’s most popular software. With almost 7 million downloads and over 600,000 users, it has been employed to construct and execute more than 3 trillion quantum circuits. Over ...

The Qiskit SDK v1.2 also includes a new unitary peephole optimization and enhancements to the Sabre algorithm, improving both the runtime and quality of transpiled circuits. These optimizations allow ...

Qiskit 1.0 enables users to build and compile circuits with 100-plus qubits, and—as indicated by IBM’s long-term quantum roadmap —it lays the groundwork for future 1,000-plus-qubit workloads.

I get the error: AttributeError: 'NoneType' object has no attribute 'clbits and it seems that the Qpy to QASM conversion failed: unable to parse quantum circuit for a circuit containing a controlled ...

Currently, noisy intermediate-scale quantum (NISQ) circuits may not always generate correct outputs due to noise and faults. In this work, we propose a diagnosis technique for NISQ circuits. The ...

You can check out the Qiskit implementation here. Quantum phase estimation (QPE) algorithm QPE is an important subroutine that serves as a central building block for many quantum algorithms. The ...
